2.1 MAC address table

2.1.1 Introduction

The MAC address table records mappings between MAC addresses and interfaces. It is the
basis for an Ethernet device to forward packets. When the Ethernet device forwards packets
on Layer 2, it searches the MAC address table for the forwarding interface, implements
expedited forwarding of packets, and reduces broadcast traffic.
The MAC address table contains the following information:
